NCT ID NCT06780215
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether varenicline tartrate, a drug typically used to help people quit smoking, can reduce frequent extra heartbeats (PVCs) in people who have had a heart attack. 116 adults aged 18-80 with a prior heart attack and at least 1,000 PVCs per day were randomly assigned to receive either varenicline or a placebo for 6 weeks, while all continued standard heart medications. The main goal was to see if varenicline could lower the number of PVCs compared to placebo.
